The managing partner of a major consulting firm is trying to assess the effectiveness of expensive computer skills training given to all new entry-level professionals. In an effort to make such an assessment, she administers a computer skills test immediately before and after the training program to each of 40 randomly chosen employees. The pre-training and post-training scores of these 40 individuals are recorded in the file P09_15.xlsx.

What about at the 1% significance level?
